idpf_vport_i..._itr_ena_irq(9)

💅 idpf_vport_i..._itr_ena_irq(9) 💅

okay so bestie, welcome to the Kernel API Manual — we're talking about idpf_vport_intr_update_itr_ena_irq(), and it's iconic in the most lowkey way. it updates itr and re-enables the MSIX interrupt for a vector. no cap, it's giving “quiet helper with main character energy.” ✨🫶

✨ NAME ✨

idpf_vport_intr_update_itr_ena_irq — Update itr and re-enable MSIX interrupt. literally what it says on the label, periodt. 💖

🌸 SYNOPSIS 🌸

the signature is exactly this, bestie, do not come for me:

void idpf_vport_intr_update_itr_ena_irq (struct idpf_q_vector *q_vector
);

🎀 ARGUMENTS 🎀

• q_vector — the q_vector for which itr is being updated and the interrupt is being enabled. that's the whole argument — one q_vector, one job. 🎀

🦋 DESCRIPTION 🦋

so what does it actually do? it updates the net_dim algorithm and re-enables the interrupt associated with this vector. that's the whole vibe: update the net_dim stuff, then turn the vector's interrupt back on. iconic behavior for a function with such a long name, honestly. 😭✨
